Application filed August 12, 1904. Serial No. 220,564.

To all ZUZL'O'IM/ it may concern:

Be it known that I, PATRICK F. DEELY, a citizen of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, have invented new and useful Improvements in Machines forCutting Scrap Metal, of which the following is a specification.

My invention relates to improvements in what may be termed machines forcutting scrap metal, whether it be alloy, iron, brass, spelter, wire,tubing, 620., also regardless of its thickness. It will be noted thatthe operation of cuttingas herein employed in dicates simply thesevering into parts, not by producing a clean incision, but more by thebreaking of the metal.

Said invention has for its object to secure this end in an expeditiousand effective manner; and it therefore consists of certain structuraldetails substantially as hereinafter more fully disclosed, andparticularly pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment'ofmy invention, Figure l is a front elevation thereof. Fig. 2 is asectional elevation, and Fig. 3 is a side elevation, of the same. Fig. 4is a detached perspective view of a cutter member enlarged. Fig. 5 is anenlarged sectional view of an endsecuring block for a cutter member.

In the carrying out of my invention I provide two rolls 1 1, onesuperposed to the other and suitably supported and journaled inposition, and requisitely arranged with relation to these rolls is asuitable feed-table 2, upon which the scrap metal is fed by hand orotherwise thereto.

The roll 1, or the lower one, has a plane face or periphery and upon itis borne the metal as it is revolved, as in similar roll mills. Theupper roll 1 has produced in its face, at suitable or short intervalsapart, longitudinal sockets or pockets 3, each extending the entirelength of said roll and each of which sockets receives or contains twocutter members3 for delivering a severing action. upon the scrap metalfed thereto, said cutter members being arranged in endwise alinement.Said sockets and cutter members are of corresponding shape and areproduced in general rectangular outline, with their lateral surfaces orwalls converging somewhat toward the roll periphery, as shown, toprevent the radial displacement of said cutter members. Said socketsopen out laterally through. the ends of said roll to permit theinsertion of said cutter members thereto. In order to retain the latteragainst lateral displacement, blocks 4:, of corresponding shape incross-section as said sockets, are inserted therein laterally of thecutter members, the latter being of less length than said sockets, saidblocks being held in place preferably by screws 4*,countersunk into saidcutter members and screwed into the roll.

. Said cutter members 3 are stepped from each outer-end rounded,conical, or salient portions 3 effective not to make a clean incisionthrough the scrap metal, but more to break itin two upon the lowerfeeding-roll carrying said metal thereunder, and suitably delivering thethus-broken-up pieces of the latter to the opposite side of saidfeeding-roll.

The machine thus described is of great and effective cutting capacity,as Well as doing its work with great expedition and celerity.

Latitude, it will be noted, is allowed as to details herein, as they maybe changed as circumstances suggest without departing from the spirit ofmy invention.

I claim 1. A machine of the character described, employing a rollequipped with longitudinal peripheral breaker members, narrowed outwardand formed with outer-end rounded effective terminals for breaking themetal and seated therein as against radial displacement.

2. A machine of the character described, employing a roll equipped withlongitudinal peripheral breaker members, seated therein as againstradial displacement and stepped from each side, forming inward-extendedshoulders, with the central portions of the steps narrowed outward andformed with outer-end rounded effective terminals for breaking themetal.

3'. A machine of the character described, employing a roll havinglongitudinal peripheral sockets and equipped with longitudinalperipheral breaker members seated in said sockets as against radialdisplacement, and stepped from each side forming inward-extendedshoulders thereon, with the central portions of the steps narrowedoutward and formed with outer-end rounded effective terminalsforbreaking the metal.

4. A machine of the character described, employing a roll equipped withlongitudinal peripheral breaker members seated therein as against radialdisplacement and stepped from each side forming inward-extendedshoulders thereon, with the central portions of the steps narrowedoutward and formed with outer-end rounded effective terminals forbreaking the metal, and a feeding-roll opposed to the afore- -'said rolland adapted to deliver said metal to, vvand :aid, said breaker membersin breaking said metal.

5. A machine of the character described, employing a roll havinglongitudinal peripheral sockets, with outward-tapered walls, and

- equipped-with longitudinal peripheralabreaker members seated in saidsockets and having their base portions of corresponding crosssectionaloutline as said sockets, said breaker members also being stepped fromboth sides,

forming inward-extended shoulders thereon. with the central portions ofthe steps narrowed outward and formed with outer-end roundedeflective'terminals for breaking the metal.

In testimony whereof I. have signed my name to this specification in-thepresence of two subscribing witnesses.
